The touch screen of a mobile phone is equivalent to a sensing device, which can receive input signals and then be driven by a tactile feedback system to produce vivid audio-visual effects on the LCD screen. The mobile phone touch screen is one of the components of the mobile phone screen. It has the advantages of being durable, easy to use, and fast in response. At present, the touch screen on the mobile phone is mainly capacitive touch screen.

The structure of the capacitive touch screen is that the glass screen is coated with a transparent film body layer, and a protective glass is added to the conductor layer. The advantage of the double glass design is that it can completely protect the conductor layer and the sensor. This structure can make the effect of the touch screen of the mobile phone better, and it will not be easily damaged.
The working principle of the capacitive touch screen is to use the electric current of the human body to sense. When the user touches the screen of the mobile phone, the electric field of the human body will form a coupling current with the surface of the touch screen of the mobile phone. Because there is a high-frequency signal connected to the touch screen of the mobile phone, a small current will be sucked from the contact point when the finger touches, and this current will be separated from the four sides of the touch screen of the mobile phone. The current in these four electrodes is proportional to the current from the finger to the four corners, so the controller can obtain the position of the touch point through accurate calculation of the four current ratios.
